CHALK-LINE REEL.

Specification of Letters Patent. Patented Aug, 31, 19 15,

Application filed October 9, 1914. Serial N0.'86 5,872.

To all whom it may concern:

Be it known that I, I'rrnnr. CHARLES RICHARDS, a citizen of the UnitedStates of America, residing at Los Angeles, in the county of Los Angelesand State of California, have invented new and useful Improvements inChalk-Line Reels, of which the following is a specification.

This invention relates to certain novel and useful improvements inchalkline reels.

In carrying outthe present invention, it is my purpose to provide achalk lin reel whereby the line may be chalked as the same is paid outfrom the reel and whereby the reel end of that portion ofthe line thatis in use may be securely fastened to the reel so as to preventaccidental unwinding of the portion of the line on the reel.

It is also my purpose to provide a chalk line reel wherein the chalkwill be carried in a cartridge disposed within the barrel of the reelwhen not in use and capable of removal from such barrel when it isdesired to use the same, the line being passed through the barrellongitudinally so that as the latter is paid out the chalk or othercoloring material within the cartridge will be applied thereto.

A further object of my invention is to provide a chalk line reel wherebythe chalk or other coloring material will be applied to the line evenlyand uniformly and witln out waste. 7

With the above and other objects in view, the invention consists in theconstruction, combination. and arrangement of parts hereinafter setforth in and falling within the scope of the claims.

In the accompanying drawings, Figure l is a view in side elevation of achalk line reel constructed in accordance with the present invention.Fig. 2 is an end elevation thereof. Fig. 3 is a longitudinal sectionalview through the same. Fig. 4 is a transverse sectional viewtherethrough. Fig. 5 is a perspective view of the chalk cartridge. Fig.6 is an enlarged fragmentary longitudinal sectional View through one endof the cartridge. Fig. 7 is a View in side elevation of a modified formof reel. Fig. 8 is a longitudinal sectional view through the reel shownin Fig. 7. Fig. 9 is a fragmentarylongitudinal sectional view showing astill further modified construction of the reel. Fig. 10is a fragmentarylongitudinal sectional View through one end ofuth reel showing amodified form of connection between the barrel and end plate; Fig. 11 1Sa plan view of one of the end plates of the reel showing a modified.form of clip.

Referring now to the drawings in detail, and particularly to the form ofmy invention illustrated in Figs. .1 to 6, inclusive, 1 designates areel comprising a barrel 2. In the present instance, the barrel 2 isformed, adjacent to the ends thereof, with annular beads 3, 3 anddisposed upon the ends of the barrel and abutting the beads 3, 3 arecircular end plates 4:, 4 respectively. The outer extremities of thebarrel are upset as at 5 and the upset portions cooperate withthe beads3 to hold the end plates 4 in proper positions on the barrel. Springclips 6, 6 are secured to the outer face of each end plate I atdiametrically opposite points.- Fastened to the outer surface of thebarrel 1 in some suitable manner and;

wrapped thereabout is the line or cord 7 adapted to be paid out frointhereel when it is desired to use the cord and after the desired length ofthe cord has been unwound from the reel, the reel end of the un-.

wound portion is clamped beneath one of the clips 6 and between thelatter and the adjacent portion of the end plate whereby accidentalunwinding of the portion of the cord on the barrel of the reel isprevented.

In order that the cord 7 may be chalked as the same is being taken fromthe reel, I employ a cartridge 8 comprising a cylindrical open endedtube 9 and hemispherical caps 10. threaded onto the ends of the.

tube 9 and closing the latter. This cartridge is designed to contain aquantity of powdered chalk 11 or other appropriate or desired markingmaterial and the ends of the caps 10 are formed with axially alining.

openings 12 through which the outer, end of the cord 7 is passed. As thecord is unwound from the reel, ,such cord is pulled through thecartridge 8 and in passing through the cartridge the coloring materialtherein is deposited on the cord,- thereby chalking or coloring thesame.

In order to insure'the even and uniform chalking of the cord and;prevent waste of the coloring matter in the cartridge, suit-F able meansis employed. In this form of my invention a felt disk 13 is disposedwithin each-cap l0and formed with an opening alining with. the adjacentopening 12 in the cap. This felt disk is pressed into thecapfio ersengaging the respective ends of the tube.

and conforms to the configuration of the inner wall thereof, whilebearing against These metallic washers 14: are preferably concavo-convexin cross section and the convexed faces thereof engage the inner facesof the felt disks 13 with the effect to maintain the felt disks in therespective caps under pressure so that any wear on the felt, incident tothe movement of the cord therethrough, will be automatically taken up,thereby preventing waste of the coloring material. This washer acts toremove any surp'lus coloring material from the cord and hold the springswithin the barrel.

thereby prevents wasteof such material.

When the cord is being taken from the reel, such cord is drawn throughthe car- 'tridge so that the marking'material is deposited thereon. Onthe other hand, when the chalk line is out of service and wrapped aboutthe barrel of the reel, the cartridge is designed to be disposed withinthe barrel 2 and for this purpose is of an exterior d1- ameter slightlyless than the interior diameter of the barrel so that the cartridgemaybe slipped into and out of the barrel quickly and evenly. To hold thecartridge Within the barrel securely and prevent rat- "tling of theparts as the device is carried from place to place appropriate means areemployed. In the present instance, longitudinally curved springs 15 aresecured to the inner surface of the barrel at diametrically oppositepoints and extend longitudinally of the barrel, rivets 16 being passedthrough the springs, centrally thereof, and through the barrel, suchrivets servinlg tfi spring 15 is of a length slightly greater 7 than thedistance between the inner ends of the caps 10 and the outer ends of thecurved spring are reversely curved as at 17 and engage the adjacentportions of the tube and the inner edges of the caps, thereby holdingthe cartridge against lateral and longitudinal movements within thetube.

In the modified form of my invention i illustrated in Figs. 7 and 8, Ihave shown site points to provide inwardly extendingthe barrel 2 stampedat diametrically oppospring fingers 18 adapted'toengage the caragainstmovement.

If desired, the retaining springs 15 within the barrel may each be of alength slightly less than that of the cartridge and have the outer;extremities thereof curved as at 19 laterally extending flange 20concentrically of the opening therein and the adjacent end of the barrelsurrounds the flange 20 and is sweated onto the same.

If desired, the spring clips 6 may be stamped from the material of theend plates as illustrated in Fig. 11.

From the foregoing description taken in connection with the accompanyingdrawing, the construction, mode of operation and manner of employing myinvention will be readily apparent. It will be seen that I have provideda chalk line reel whereby the cord will be confined within the spacebetween the end plates of the barrel when wound on the latter andwhereby such cord may be chalked when drawn fromthe reel.

I claim:

1. In a device of the class described, a reel comprising a barrel, endplates secured to the extremities of said barrel, a cord wrapped aboutsaid barrel and adapted to be unwound therefrom, and a chalk carryingcartridge through which the outer end of said cord is passed disposedwithin said barrel and adapted to be removed therefrom in the unwindingof the cord so that the latter may be drawn through the barrel to chalkthe same.

Ina device of the class described, a
